You can get the ISO Live images from the Mint 16 Download page but please remember, at the time of this writing, the KDE and Xfce versions are still 'release candidates', the final versions will appear sometime in the next few days or weeks.

The images are fairly large, ranging from just over 1.2GB to just under 1.5GB, so they will certainly not fit on a CD, they require either a DVD or a 2GB or larger USB stick. These are hybrid images, so if you already have a Linux system you can simply dd them to a USB stick; otherwise you can use the windows Image Writer to accomplish the same task. For details on this, Clem has written a very concise How to install Linux Mint via USB tutorial.
